Now let us suppose that we have a variable with categorical values in { X }. someone who has attained wisdom

"Webis known as recursive binary splitting. The approach is top-down because it begins at the top of the tree and then successively splits the predictor space; each split is indicated via two new branches further down on the tree. It is greedy because at each step of the tree-building process, the best split is made at that particular step, " - Binary splitting

In mathematics, binary splitting is a technique for speeding up numerical evaluation of many types of series with rational terms. In particular, it can be used to evaluate hypergeometric series at rational points. See more Given a series $${\displaystyle S(a,b)=\sum _{n=a}^{b}{\frac {p_{n}}{q_{n}}}}$$ where pn and qn are integers, the goal of binary splitting is to compute integers P(a, b) and Q(a, b) such … See more Binary splitting requires more memory than direct term-by-term summation, but is asymptotically faster since the sizes of all occurring subproducts are reduced.
